If you have the stock tire size, then whatever it says on the door sticker.

 

Far as I know and learned, you should always go with this. Dealerships and tireshops usually do too. I've always done it and never had a problem with it. Doesn't mean it right or wrong though. Anything's possible on this site.

 

you should have a sticker on the inside of the fuel door, i believe it says 30 psi at all 4 corners. i fill mine up at 30-32. 40 is wayyy too high.

 

No way. You won't be running on the whole tire if you do it that high.

I usually fill mine to about 32ish. My guage sucks, so it's usually around 30-34 or something.
